Abstract (en)
[origin: WO2018068840A1] A method for controlling a velocity of a conveyance path of a system (1 1 ) including an industrial robot (2), a first conveyance path (4) configured to transfer items (5) within a working area (b2) of the robot (2) with a velocity vi, and a second conveyance path (6) configured to transfer empty places (7) within the working area (b2) of the robot (2) with a velocity V2. The method includes: obtaining position data for a plurality of items (5) and for a plurality of empty places (7); creating one or more pairs including one of the empty places (7) of the plurality of empty places (7) and a respective item (5) of the plurality of items (5); calculating, for one of the one or more pairs, a time tAs for the empty place (7) of the one pair and a time tBk for the item (5) of the one pair to reach a border (16, 17) of the working area (b2) based on position data for the one pair and the velocities vi and V2; and controlling the velocity V2 of the second conveyance path (6) based on a difference between the time tAs and a time (tBk+At), where At is a predetermined time difference.
